Requesting Entity: Davao City Water District

Issues Concern: Clarification on Variation Order - Extra Work Order



Costing of additional materials involving new work items that are not in the original contract or Extra Work Order of an infrastructure project.

[T]he costing of the additional materials for the Extra Work Order would depend on whether said materials are the same as in the original contract or not. The unit price of additional materials, which are exactly the same or similar to those in the original contract, shall be based on the unit price of said materials in the original contract. However, the unit price for new components or materials shall be based on the contractor's estimate as validated by the procuring entity through canvass.
